Mesa Boogie v-twin repair

Anyone ever take one of these apart, mines got a cracking pot I need to fix -
looking for pointers / pitfalls
I did a bit of googling and could not find any
instructions, apart from a few people saying they were a bitch to get apart
Trying my fav forum first, if no replies will see if there is a specific mesa forum
anywhere and then post there
Thanks

V-Twin... Still on my wish list after all these years  Never had one in pieces though, so can't help there. I'm sure the schematics are easy to
find but I've never seen a service manual on my travels. In my experience the
degree of difficulty in taking things apart has little to do with the actual equipment and
everything to do with the person doing it. The more things you strip down and rebuild, the
easier they get. However, if it's just a crackling pot you might be able to get
it fixed without dismantling. A few careful applications of switch cleaner to the point
where the pot shaft comes through the threaded sleeve might do it for you, capillary
action might well draw enough down the shaft into the pot to get it cleaned and lubed. Andy

Thanks Zen
I did consider your suggestion but was wary that I could
end up with fluid on the circuit board etc... and possibly cause a short.
The
problem I think is lack of use. When I was playing live it got used at least twice a week.
Now it just comes out from time to time. Its quite nice to use as a pre for a bass.

No need to worry Greg. Apply a little at a time rather than flooding it, give it a minute
or so to work through and then rotate the pot a few times to wipe the track. Then leave it
for 30 mins or so to dry out. Andy

+1 on the switch cleaner.
I've got a V Twin and they sound great for what
they do. Works straight into a decent Pre for that Mesa Sound. Great on Bass too.
Collectors items now?
BTW I think I got mine for £80 quid on the
bay. Bargain. Built like tanks!

Thanks for the advice guys
I have given the unit a squirt and the knobs a
twiddle this evening and will leave over night before trying tomorrow
@
_Six_ i was quite surprised to find one on ebay with a buy now price of £335 so you
may be right in terms of collectability. Last time I looked was some 6 years ago and they
were regularly selling for £250 so you got a bargain. I have had mine from new so paid
full price.

Mine's the Mark I without the adjustment switch on the base of the unit. I've played about
with different rated tubes but still say the stock Mesa 12AX7's sound the best.
They should reissue that pedal.. It's legendary!

A quick report back and a thankyou to Zen for his method - no more scratchy
pots 
and no need to take the v-twin apart
